There's a story of a student from a developing country. With limited educational resources locally, Coursera was a boon. They took courses in environmental science. After that, they were able to contribute to local environmental projects and also got accepted into a prestigious international university for a related master's program. Coursera opened up new horizons for them and allowed them to pursue their dreams despite the odds. They were able to connect with the global academic community and bring back valuable knowledge to their own community.

One SQL horror story could be when a developer accidentally dropped an important table in the production database. They might have mis-typed a command like 'DROP TABLE' instead of something else. This led to a huge loss of data and hours of downtime to try and restore from backups.

Another success story is about a young professional who was feeling stagnant in his current role. He enrolled in Coursera's business courses. By networking with peers in the course forums and applying the knowledge he learned, he was able to propose new strategies at his workplace. This led to him getting promoted and taking on more leadership roles within his company. Coursera not only gave him the knowledge but also the confidence to step up in his career.

One horror story is about a major data loss during a system upgrade. The upgrade process had some untested scripts that ended up deleting crucial data tables instead of modifying them. It was a nightmare as there was no proper backup strategy in place. The company had to spend weeks trying to recover what they could from old backups and logs.

A common horror story is performance issues. For example, a query that was supposed to run in seconds took hours. This was due to bad indexing. Indexes were not created properly or were missing for important columns used in the WHERE clause of the query. Another is security breaches. If a SQL Server has weak authentication or improper user permissions, it can be easily hacked. Hackers can then steal sensitive data like customer information or financial records.

Poorly written SQL queries can also lead to horror stories. For example, queries with incorrect joins can result in wrong data being retrieved or updated. If a developer doesn't fully understand how to use JOINs correctly, it can mess up the whole data integrity.

A table was a commonly used data storage method in an SQL database. A table usually contains a set of related data elements, which are established by association. Each table has a unique name that is used to identify the relationship between the tables. You can use tables, views, stored procedures, and other tools to manage the information in the database. A table is a basic database data structure and one of the most commonly used data types in the SQL language.
